Abstract

Description

The present application is in the field of cosmetics and relates to a method for the treatment of keratinic material, in particular human hair, which comprises the use of two compositions (A) and (B). The composition (A) is a low-water preparation which contains at least one organic C ₁ -C ₆ -alkoxysilane, and the composition (B) contains, in addition to water, at least one nonionic surfactant.

A second subject of the present invention is a multi-component packaging unit (kit-of-parts) for coloring keratinous material, which, separately packaged in two packaging units, comprises the two compositions (A) and (B) described above

The change in the shape and color of keratinic fibers, in particular of hair, represents an important area of modern cosmetics. The person skilled in the art knows various coloring systems for changing the hair color, depending on the coloring requirements. Oxidation dyes are usually used for permanent, intense dyeings with good fastness properties and good gray coverage. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes with one another. Oxidation dyes are characterized by very long-lasting coloring results.

If substantive dyes are used, dyes that have already been developed diffuse from the dye into the hair fiber. Compared to oxidative hair coloring, the coloring obtained with substantive dyes is less durable and can be washed out more quickly. Colorations with substantive dyes usually remain on the hair for a period of between 5 and 20 washes.

The use of color pigments is known for brief color changes on the hair and / or the skin. Color pigments are generally understood to mean insoluble, coloring substances. These are present undissolved in the form of small particles in the coloring formulation and are only deposited on the outside of the hair fibers and / or the skin surface. Therefore, they can usually be removed without residue by a few washes with detergents containing surfactants. Various products of this type are available on the market under the name of hair mascara.

If the user wants particularly long-lasting coloring, the use of oxidative coloring agents has so far been his only option. However, despite multiple attempts at optimization, an unpleasant smell of ammonia or amine cannot be completely avoided with oxidative hair coloring. The hair damage still associated with the use of oxidative coloring agents also has an adverse effect on the user's hair.

EP 2168633 B1 deals with the task of producing long-lasting hair color using pigments. The document teaches that when a combination of pigment, organic silicon compound, hydrophobic polymer and a solvent is used, hair can be colored which is particularly resistant to shampooing.

In the EP 2168633 B1 The organic silicon compounds used are reactive compounds from the class of alkoxy-silanes. These alkoxy-silanes hydrolyze in the presence of water at high speed and - depending on the particular amounts of alkoxy-silane and water used - form hydrolysis products and / or condensation products. The influence of the amount of water used in this reaction on the properties of the hydrolysis or condensation product are for example in WO 2013068979 A2 described.

If these alkoxy-silanes or their hydrolysis or condensation products are used on keratin material, a film or also a coating forms on the keratin material, which completely envelops the keratin material and in this way strongly influences the properties of the keratin material. Possible areas of application are, for example, permanent styling or the permanent change in shape of keratin fibers. Here the keratin fibers are mechanically brought into the desired shape and then fixed in this shape by forming the above-described coating. Another very particularly suitable application is the coloring of keratin material; In the context of this application, the coating or the film is in the presence of a coloring compound, for example a Pigments. The film colored by the pigment remains on the keratin material or the keratin fibers and results in surprisingly wash-resistant colorations.

The great advantage of the alkoxy-silane-based coloring principle is that the high reactivity of this class of compounds enables very fast coating. In this way, extremely good staining results can be achieved after a very short application period of just a few minutes. In addition to these advantages, the high reactivity of the alkoxy silanes also has some disadvantages.

Due to their high reactivity, the organic alkoxy-silanes cannot be made up together with larger amounts of water, since a large excess of water initiates immediate hydrolysis and subsequent polymerization. The polymerization which takes place when the alkoxy-silanes are stored in an aqueous medium is expressed in a thickening or gelling of the aqueous preparation. This makes the preparations so highly viscous, gel-like or gelatinous that they can no longer be applied evenly to the keratin material. In addition, the storage of the alkoxy-silanes in the presence of large amounts of water is associated with a loss of their reactivity, so that the formation of a resistant coating on the keratin material is no longer possible.

For these reasons, it is necessary to store the organic alkoxy-silanes in an anhydrous or low-water environment and to pack the corresponding preparations in a separate container. Due to their high reactivity, the alkoxy silanes can react not only with water, but also with other cosmetic ingredients. In order to avoid all undesirable reactions, the preparations with alkoxy-silanes therefore preferably contain no further ingredients or only the selected ingredients which have been found to be chemically inert to the alkoxy-silanes. The concentration of the alkoxy silanes in the preparation is accordingly preferably chosen to be relatively high. The low-water preparations, which contain the alkoxy-silanes in relatively high concentrations, can also be referred to as “silane blends”.

For application to the keratin material, the user now has to convert this relatively highly concentrated silane blend into a ready-to-use mixture. In this ready-to-use mixture, on the one hand, the concentration of the organic alkoxy-silanes is reduced and, on the other hand, the application mixture also contains a higher proportion of water (or an alternative ingredient), which triggers the polymerization leading to the coating.

It has been found to be extremely challenging to control the rate of polymerization, i. the speed at which the coating is formed on the keratin material can be optimally adapted to the application conditions.

When used on human hair, a polymerization rate that is too fast leads, for example, to the polymerization being completed before all parts of the hair could be treated. Too rapid a polymerization therefore makes the whole head treatment impossible. In the dyeing process, the too rapid polymerization manifests itself in an extremely uneven color result, so that the hair that was last treated is only poorly colored.

If the polymerisation is too slow, on the other hand, all areas of the hair can be treated without time pressure, but this increases the duration of use. If the polymerization is too slow, the great advantage of this dyeing technology, the formation of washfast dyeings within a very short period of use, does not come into play.

It was the object of the present application to find a method for treating keratinic material by means of which the polymerization rate of the organic alkoxysilanes could be adapted to the conditions of use, in particular to the conditions prevailing when used on the human head. In other words, a process was sought by which the organic alkoxysilanes remained reactive for so long that a whole-head treatment is made possible without unduly extending the application period.

It has surprisingly been found that this object can be achieved in full if the keratin material is treated in a method in which two compositions (A) and (B) are applied to the keratin material. The first composition (A) is the low-water silane blend described above. The second composition (B) contains water and also contains at least one nonionic surfactant. When using both compositions (A) and (B) in contact with one another, this contact being possible either by prior mixing of (A) and (B) or by successive application of (A) and (B) to the keratin material.

• - eine erste Zusammensetzung (A), die - bezogen auf das Gesamtgewicht der Zusammensetzung (A) - enthält (A1) weniger als 10 Gew.-% Wasser und (A2) ein oder mehrere organische C₁-C₆-Alkoxy-Silane und/oder deren Kondensationsprodukte, und
• - eine zweite Zusammensetzung (B), die enthält (B1) Wasser und (B2) ein oder mehrere nichtionische Tenside.

A first object of the present invention is a method for treating keratinic material, in particular human hair, in which the keratinic material is used

• - A first composition (A) which - based on the total weight of the composition (A) - contains (A1) less than 10% by weight of water and (A2) one or more organic C ₁ -C ₆ -alkoxy-silanes and / or their condensation products, and
• - A second composition (B) which contains (B1) water and (B2) one or more nonionic surfactants.

• - eine erste Zusammensetzung (A), die - bezogen auf das Gesamtgewicht der Zusammensetzung (A) - enthält (A1) weniger als 10 Gew.-% Wasser und (A2) ein oder mehrere organische C₁-C₆-Alkoxy-Silane, und
• - eine zweite Zusammensetzung (B), die enthält (B1) Wasser und (B2) ein oder mehrere nichtionische Tenside.

A first object of the present invention is a method for treating keratinic material, in particular human hair, in which the keratinic material is used

• - A first composition (A) which - based on the total weight of the composition (A) - contains (A1) less than 10% by weight of water and (A2) one or more organic C ₁ -C ₆ -alkoxy-silanes, and
• - A second composition (B) which contains (B1) water and (B2) one or more nonionic surfactants.

It has been shown that the nonionic surfactants (B2) contained in the water-containing composition (B) reduce the rate of polymerization of the organic C ₁ -C ₆ -alkoxy-silanes (A2) on contact with the composition (A). Surprisingly, the reactivity of the organic C ₁ -C ₆ -alkoxy-silanes (A2) could thus be optimally adapted to the application conditions prevailing in a full-head hair dyeing process. Even more complicated or more time-consuming coloring techniques, such as the coloring of highlights specially arranged on the head, could be implemented using the method according to the invention. When using the two compositions (A) and (B) in a coloring process on keratin material, in particular on human hair, it was possible in this way to produce colorations with particularly high uniformity.

Treatment of keratinic material

Keratinic material is understood to mean hair, skin, and nails (such as fingernails and / or toenails, for example). Furthermore, wool, furs and feathers also fall under the definition of keratinic material.

Keratinic material is preferably understood to mean human hair, human skin and human nails, in particular fingernails and toenails. Keratinic material is very particularly preferably understood to mean human hair.

Agents for treating keratinous material are understood to mean, for example, means for coloring the keratin material, means for reshaping or shaping keratinic material, in particular keratinic fibers, or also means for conditioning or maintaining the keratinic material. The agents produced by the process according to the invention are particularly suitable for coloring keratinic material, in particular for coloring keratinic fibers, which are particularly preferably human hair.

The term “means for coloring” is used in the context of this invention for a coloring of the keratin material, especially the hair, caused by the use of coloring compounds, such as thermochromic and photochromic dyes, pigments, mica, substantive dyes and / or oxidation dyes. With this coloring, the aforementioned coloring compounds are deposited in a particularly homogeneous and smooth film on the surface of the keratin material or diffuse into the keratin fiber. The film is formed in situ by oligomerization or polymerization of the organic alkoxy silane (s), and by the interaction of the coloring compound and the organic silicon compound and, optionally, further constituents, such as a film-forming polymer.

Water content (A1) in the composition (A)

The method according to the invention is characterized by the use of a first composition (A) on the keratinic material.

In order to ensure a sufficiently high storage stability, the composition (A) is characterized in that it is low in water, preferably essentially free of water. The composition (A) therefore contains less than 10% by weight of water, based on the total weight of the composition (A).

With a water content of just below 10% by weight, the compositions (A) are storage-stable over long periods of time. In order to improve the storage stability even further and to ensure a sufficiently high reactivity of the organic C ₁ -C ₆ -alkoxy-silanes (A2), however, it has been found to be particularly preferred to lower the water content in the composition (A) even further . For this reason, the first composition (A) contains - based on the total weight of the composition (A) - preferably 0.01 to 9.5% by weight, more preferably 0.01 to 8.0% by weight, even more preferably 0.01 to 6.0 and very particularly preferably 0.01 to 4.0% by weight of water (A1).

In the context of a very particularly preferred embodiment, a method according to the invention is characterized in that the first composition (A) - based on the total weight of the composition (A) - 0.01 to 9.5% by weight, preferably 0.01 to 8 , 0% by weight, more preferably 0.01 to 6.0 and very particularly preferably 0.01 to 4.0% by weight of water (A1).

Organic C ₁ -C ₆ -alkoxy-silanes (A2) and / or their condensation products in the composition (A)

The composition (A) is characterized in that it contains one or more organic C ₁ -C ₆ -alkoxy-silanes (A2) and / or their condensation products.

The organic C ₁ -C ₆ -alkoxy-silane (s) are organic, non-polymeric silicon compounds which are preferably selected from the group of silanes having one, two or three silicon atoms

Organic silicon compounds, which are alternatively referred to as organosilicon compounds, are compounds that either have a direct silicon-carbon bond (Si-C) or in which the carbon is attached to the silicon via an oxygen, nitrogen or sulfur atom. Atom is linked. The organic silicon compounds according to the invention are preferably compounds which contain one to three silicon atoms. The organic silicon compounds particularly preferably contain one or two silicon atoms.

According to the IUPAC rules, the term silane stands for a group of chemical compounds based on a silicon backbone and hydrogen. In the case of organic silanes, the hydrogen atoms have been completely or partially replaced by organic groups such as, for example, (substituted) alkyl groups and / or alkoxy groups.

A characteristic of the C ₁ -C ₆ -alkoxy-silanes according to the invention is that at least one C ₁ -C ₆ -alkoxy group is bonded directly to a silicon atom. The C ₁ -C ₆ -alkoxy-silanes according to the invention thus comprise at least one structural unit R'R "R"'Si-O- (C ₁ -C ₆ -alkyl) where the radicals R', R "and R"'represent the three remaining bond valences of the silicon atom.

The C ₁ -C ₆ alkoxy group or groups bonded to the silicon atom are very reactive and are hydrolyzed at high speed in the presence of water, the reaction rate also depending, inter alia, on the number of hydrolyzable groups per molecule. If the hydrolyzable C ₁ -C ₆ -alkoxy group is an ethoxy group, the organic silicon compound preferably contains a structural unit R'R "R"'Si-O-CH2-CH3. The radicals R ', R "and R"' again represent the three remaining free valences of the silicon atom.

Even the addition of small amounts of water initially leads to hydrolysis and then to a condensation reaction of the organic alkoxysilanes with one another. For this reason, both the organic alkoxysilanes (A2) and their condensation products can be included in the composition.

A condensation product is understood to mean a product that is formed by the reaction of at least two organic C ₁ -C ₆ -alkoxy-silanes with elimination of water and / or with elimination of a C ₁ -C ₆ -alkanol.

The condensation products can be, for example, dimers, but also trimers or oligomers, the condensation products being in equilibrium with the monomers.

Depending on the amount of water used or consumed in the hydrolysis, the equilibrium shifts from monomeric C ₁ -C ₆ -alkoxysilane to condensation product.

In a particularly preferred embodiment, a method according to the invention is characterized in that the composition (A) contains one or more organic C ₁ -C ₆ -alkoxy-silanes (A2) which are selected from silanes with one, two or three silicon atoms wherein the organic silicon compound further comprises one or more basic chemical functions.

This basic group can be, for example, an amino group, an alkylamino group or a dialkylamino group, which is preferably connected to a silicon atom via a linker. The basic group is preferably an amino group, a C ₁ -C ₆ -alkylamino group or a di (C ₁ -C ₆ ) alkylamino group.

A very particularly preferred method according to the invention is characterized in that the composition (A) contains one or more organic C ₁ -C ₆ -alkoxy-silanes (A2) which are selected from the group of silanes with one, two or three silicon atoms, and wherein the C ₁ -C ₆ -alkoxy-silanes further comprise one or more basic chemical functions.

Very particularly good results could be obtained if C ₁ -C ₆ -alkoxy-silanes of the formula (SI) and / or (S-II) were used in the process according to the invention. Since, as already described above, hydrolysis / condensation begins even with traces of moisture, the condensation products of the C ₁ -C ₆ -alkoxy-silanes of the formula (SI) and / or (S-II) are also included in this embodiment.

The use of hexamethyldisiloxane in composition (A) has proven to be very particularly preferred. Hexamethyldisiloxane is particularly preferred - based on the total weight of the composition (A) - in amounts of 10.0 to 50.0% by weight, preferably 15.0 to 45.0% by weight, more preferably 20.0 to 40% , 0% by weight, even more preferably 25.0 to 35.0% by weight and very particularly preferably 31.0 to 34.0% by weight in the composition (A).

In a further very particularly preferred embodiment, a method according to the invention is characterized in that the first composition (A) - based on the total weight of the composition (A) - 10.0 to 50.0% by weight, preferably 15.0 to 45% , 0% by weight, more preferably 20.0 to 40.0% by weight, even more preferably 25.0 to 35.0% by weight and very particularly preferably 31.0 to 34.0% by weight of hexamethyldisiloxane contains.

Water content (B1) in the composition (B)

The method according to the invention is characterized by the use of a second composition (B) on the keratinic material, in particular on human hair.

When used on the keratinous material, the compositions (A) and (B) come into contact, it being possible for this contact to be established very particularly preferably by previously mixing the two compositions (A) and (B). By mixing (A) and (B) the ready-to-use keratin treatment agent is produced, i. the storage-stable or storable silane blend (A) is converted into its reactive form by contact with (B). When the compositions (A) and (B) are mixed, a polymerization reaction starting from the alkoxy-silane monomers or alkoxy-silane oligomers starts, which finally leads to the formation of the film or the coating on the keratin material.

The more water comes into contact with the organic C ₁ -C ₆ -alkoxy-silane (s), the greater the extent to which the polymerization reaction takes place. For example, if the composition (B) contains a great deal of water, the monomeric or oligomeric silane condensates previously present in the low-water composition (A) now polymerize very quickly to give polymers of relatively high or high molecular weight. The high molecular weight silane polymers then form the film on the keratinic material. For this reason, water (B1) is an essential ingredient of the composition (B).

The rate of polymerization of the organic C ₁ -C ₆ -alkoxy-silanes (A2) at the time of use can also be determined by the amount of water in the composition (B). In order to ensure a uniform color result when coloring the hair over the entire head, the rate of polymerization, ie the rapidity with which the coating is formed, should not be too high either. For this reason, it has been found to be particularly preferred not to choose too high the amount of water in the composition (B).

Particularly uniform colorations on the entire head could be obtained if the composition (B) - based on the total weight of the composition (B) - 5.0 to 90.0% by weight, preferably 15.0 to 85.0% by weight. -%, more preferably 25.0 to 80.0% by weight, even more preferably 35.0 to 75.0% by weight and very particularly preferably 45.0 to 70.0% by weight of water (B1) contains.

In a further very particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - 5.0 to 90.0% by weight, preferably 15.0 to 85% , 0% by weight, more preferably 25.0 to 80.0% by weight, even more preferably 35.0 to 75.0% by weight and very particularly preferably 45.0 to 70.0% by weight Contains water (B1).

Nonionic surfactants in the composition (B)

Another characteristic of the composition (B) is its content of at least one nonionic surfactant (B2).

Surprisingly, it has been found that the use of at least one nonionic surfactant (B2) optimizes the reaction rate of the organic C ₁ -C ₆ -alkoxysilanes in such a way that uniform coloring is made possible over the entire head.

Due to its water (B1) and nonionic surfactant (B2) content, the composition (B) is in the form of an emulsion. Without being tied to this theory, it is assumed that the C ₁ -C ₆ -alkoxysilanes (A2) are embedded in the micelles or the hydrophobic areas of the emulsion. In this way, the direct environment of the C ₁ -C ₆ -alkoxysilanes (A2) is rendered hydrophobic. Since it is assumed that the hydrolysis and / or the condensation reaction rate of the C ₁ -C ₆ -alkoxysilanes proceeds more slowly in a non-polar environment, the reactivity of the C ₁ -C ₆ -alkoxysilanes can be reduced in this way and the formation of the film or coating be slowed down on the keratin material.

The term surfactants (T) is understood to mean surface-active substances which form adsorption layers on surfaces and interfaces or can aggregate in volume phases to form micellar colloids or lyotropic mesophases. In general, the person skilled in the art distinguishes between anionic surfactants consisting of a hydrophobic radical and a negatively charged hydrophilic head group, amphoteric surfactants which have both a negative and a compensating positive charge, cationic surfactants which have a positively charged hydrophilic group in addition to a hydrophobic radical, and nonionic ones Surfactants which have a hydrophobic residue and furthermore no charges, but rather molecular groups with strong dipole moments which are strongly hydrated in aqueous solution.

They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably from glucose. The preferred Alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (Tnio-2) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p in the individual molecule must always be an integer and is given here can assume the values p = 1 to 6 in particular, the value p for a specific alkyl oligoglycoside is an analytically determined mathematical variable that usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4 are preferred. The alkyl or alkenyl radical R ⁴ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms.

The fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose. The preferred fatty acid N-alkyl polyhydroxyalkylamides are therefore fatty acid N-alkyl glucamides as represented by the formula (Tnio-4): R ⁷ CO- (NR ⁸ ) -CH ₂ - [CH (OH)] ₄ - CH ₂ OH (Tnio-4)

A particularly suitable nonionic surfactant (B2) of this type is, for example, a- [3,5-dimethyl-1 - (2-methylpropyl) hexyl] -w-hydroxy-poly (oxy-1,2-ethanediyl), which under the Trade names Polyethylene glycol trimethylnonyl ether; Polyoxyethylene 2,6,8-trimethyl-4-nonyl ether; Polyoxyethylene trimethyl nonyl ether; Surfactant WK; TMN 10; TMN 3; TMN 6; TX 3; TX 3 (polyoxyalkylenes); TX 6; Tergitol 100; Tergitol TMN; Tergitol TMN 10; Tergitol, TMN 100X; Tergitol TMN 3; Tergitol TMN 6 or trimethylnonanol polyethylene glycol can be purchased commercially.

By choosing the appropriate amounts of nonionic surfactants (B2) used, the rate of film formation starting from the C ₁ -C ₆ -alkoxy-silanes can be determined particularly strongly. For this reason it has proven to be very particularly preferred to use one or more nonionic surfactants (B2) in very specific quantity ranges.

It is very particularly preferred if the second composition (B) - based on the total weight of the composition (B) - has one or more nonionic surfactants (B2) in a total amount of 0.5 to 20.0% by weight, preferably of 1.0 to 10.0% by weight, more preferably from 1.5 to 8.0% by weight and very particularly preferably from 2.0 to 7.0% by weight.

Fat components in the composition (B)

In addition to the nonionic surfactants (B2), the composition (B) can optionally also contain one or more further hydrophobic constituents or fat constituents.

The fat components are also hydrophobic substances which, in the presence of water, can form emulsions with the formation of micelle systems. In analogy to the terpenes, it is also assumed in this context that the C ₁ -C ₆ -alkoxysilanes - either in the form of their monomers or optionally in the form of their condensed oligomers - in this hydrophobic environment or in the Micellar systems are embedded so that the polarity of their surroundings changes. Due to the hydrophobic character of the fat constituents, the area around the C ₁ -C ₆ alkoxysilanes is also rendered hydrophobic. It is assumed that the polymerization reaction of the C ₁ -C ₆ -alkoxysilanes leading to the film or coating takes place in an environment of reduced polarity with reduced speed.

The fat constituents contained in the composition (B) are most preferably selected from the group of C ₁₂ -C ₃₀ fatty alcohols, C ₁₂ -C ₃₀ fatty acid triglycerides, the C ₁₂ -C ₃₀ -Fettsäuremonoglyceride, the C ₁₂ -C ₃₀ -Fatty acid diglycerides and / or the hydrocarbons.

In this connection it has been found that the use of at least one C ₁₂ -C ₃₀ fatty alcohol in particular in the composition (B) creates an emulsion system in which the alkoxysilanes (A2) can be embedded particularly well.

By choosing the appropriate amounts of C ₁₂ -C ₃₀ fatty alcohols used, the rate of film formation starting from the C ₁ -C ₆ -alkoxy-silanes can be particularly strongly influenced. For this reason, it has proven to be very particularly preferred to use one or more C ₁₂ -C ₃₀ fatty alcohols in very specific quantity ranges.

Unsaturated fatty acids can be monounsaturated or polyunsaturated. In the case of an unsaturated fatty acid, its CC double bond (s) can have the cis or trans configuration.

The fatty acid triglycerides are characterized by their particular suitability, in which at least one of the ester groups is formed starting from glycerol with a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (Stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z) -6-octadecenoic acid], palmitoleic acid [(9Z) -hexadec-9-enoic acid], oleic acid [(9Z) - Octadec-9-enoic acid], elaidic acid [(9E) -octadec-9-enoic acid], erucic acid [(13Z) -Docos-13-enoic acid], linoleic acid [(9Z, 12Z) -octadeca-9,12-dienoic acid, linolenic acid [(9Z, 12Z, 15Z) -Octadeca-9,12,15-trienoic acid, eleostearic acid [(9Z, 11E, 13E) -Octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z, 8Z, 11Z, 14Z ) -Icosa-5,8,11,14-tetraenoic acid] and / or nervonic acid [(15Z) -Tetracos-15-enoic acid].

The fatty acid triglycerides can also be of natural origin. The fatty acid triglycerides or mixtures thereof occurring in soybean oil, peanut oil, olive oil, sunflower oil, macadamia nut oil, moringa oil, apricot kernel oil, marula oil and / or optionally hydrogenated castor oil are particularly suitable for use in the product according to the invention.

A C ₁₂ -C ₃₀ fatty acid monoglyceride is understood as meaning the monoester of the trihydric alcohol glycerol with one equivalent of fatty acid. Either the middle hydroxyl group of the glycerol or the terminal hydroxyl group of the glycerol can be esterified with the fatty acid.

A C ₁₂ -C ₃₀ fatty acid diglyceride is understood as meaning the diester of the trihydric alcohol glycerol with two equivalents of fatty acid. Either the middle and one terminal hydroxyl group of the glycerol can be esterified with two equivalents of fatty acid, or both terminal hydroxyl groups of the glycerol are esterified with one fatty acid each. The glycerine can be esterified with two structurally identical as well as with two different fatty acids.

The fatty acid diglycerides are characterized by their particular suitability, in which at least one of the ester groups is formed from glycerol with a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (Stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z) -6-octadecenoic acid], palmitoleic acid [(9Z) -hexadec-9-enoic acid], oleic acid [(9Z) -octadec-9-enoic acid] , Elaidic acid [(9E) -octadec-9-enoic acid], erucic acid [(13Z) -Docos-13-enoic acid], linoleic acid [(9Z, 12Z) -octadeca-9,12-dienoic acid, linolenic acid [(9Z, 12Z, 15Z) -Octadeca-9,12,15-trienoic acid, eleostearic acid [(9Z, 11E, 13E) -Octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z, 8Z, 11Z, 14Z) -Icosa-5, 8,11,14-tetraenoic acid] and / or nervonic acid [(15Z) -Tetracos-15-enoic acid].

Very particularly good results were obtained when the composition (B) contained at least one C ₁₂ -C ₃₀ fatty acid monoglyceride, which is selected from the monoesters of glycerol with one equivalent of fatty acid from the group of dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), Hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselic acid [(Z) -6-octadecenoic acid], palmitoleic acid [(9Z) -hexadec-9-oleic acid] [(9Z) -Octadec-9-enoic acid], elaidic acid [(9E) -octadec-9-enoic acid], erucic acid [(13Z) -Docos-13-enoic acid], linoleic acid [(9Z, 12Z) -octadeca-9, 12-dienoic acid, linolenic acid [(9Z, 12Z, 15Z) -octadeca-9,12,15-trienoic acid, eleostearic acid [(9Z, 11E, 13E) -octadeca-9,11,3-trienoic acid], arachidonic acid [(5Z, 8Z, 11Z, 14Z) -Icosa-5,8,11,14-tetraenoic acid] and / or nervonic acid [(15Z) - tetracos-15-enoic acid].

In a very particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one C ₁₂ -C ₃₀ fatty acid monoglyceride which is selected from the monoesters of glycerol with one equivalent of fatty acid from the group of dodecanoic acid, Tetradecanoic acid, hexadecanoic acid, tetracosanoic acid, octadecanoic acid, eicosanoic acid and / or docosanoic acid.

The rate of the C ₁ -C ₆ -alkoxy-silanes can also be increased by choosing the appropriate amounts of C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ -C ₃₀ fatty acid di- and / or C ₁₂ -C ₃₀ fatty acid triglycerides Film formation are particularly strongly influenced. Because of this, it has proven to be very special proved to be preferred to use one or more C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ -C ₃₀ fatty acid di- and / or C ₁₂ -C ₃₀ fatty acid triglycerides in very specific quantity ranges in the composition (B).

With a view to solving the problem according to the invention, it has proven to be particularly preferred if the second composition (B) - based on the total weight of the composition (B) - has one or more C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ - C ₃₀ fatty acid di- and / or C ₁₂ -C ₃₀ fatty acid triglycerides in a total amount of 0.1 to 20.0% by weight, preferably 0.3 to 15.0% by weight, more preferably 0.5 to 10 , 0 wt .-% and very particularly preferably from 0.8 to 5.0 wt .-%.

In a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - has one or more C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ -C ₃₀ - Fatty acid di and / or C ₁₂ -C ₃₀ fatty acid triglycerides in a total amount of 0.1 to 20.0% by weight, preferably 0.3 to 15.0% by weight, more preferably 0.5 to 10.0% by weight .-% and very particularly preferably from 0.8 to 5.0% by weight.

The C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ -C ₃₀ fatty acid di- and / or C ₁₂ -C ₃₀ fatty acid triglycerides can be used as the sole fat constituents in the compositions (B). However, it is very particularly preferred to add at least one C ₁₂ -C ₃₀ fatty acid mono-, C ₁₂ -C ₃₀ fatty acid di and / or C ₁₂ -C ₃₀ fatty acid triglyceride in combination with at least one C ₁₂ -C ₃₀ fatty alcohol To incorporate composition (B).

Composition (B) can also contain at least one hydrocarbon as a very particularly preferred fat component.

Hydrocarbons are compounds with 8 to 80 C atoms that consist exclusively of carbon and hydrogen. In this context, aliphatic hydrocarbons such as mineral oils, liquid paraffin oils (e.g. Paraffinium Liquidum or Paraffinum Perliquidum), isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (Paraffinum Solidum), petrolatum and polydecene are particularly preferred.

Liquid paraffin oils (Paraffinum Liquidum and Paraffinium Perliquidum) have proven to be particularly suitable in this context. The hydrocarbon is very particularly preferably Paraffinum Liquidum, also called white oil. Paraffinum Liquidum is a mixture of purified, saturated, aliphatic hydrocarbons, which mostly consists of hydrocarbon chains with a carbon chain distribution of 25 to 35 carbon atoms.

Particularly good results were obtained when the composition (B) contained at least one hydrocarbon selected from the group of mineral oils, liquid paraffin oils, isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (Paraffinum Solidum), petrolatum and polydecene.

In a very particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) contains at least one fat component from the group of hydrocarbons.

The rate of the film formation starting from the C ₁ -C ₆ -alkoxy-silanes can also be influenced to a particularly large extent by choosing the suitable amounts of hydrocarbons used. For this reason it has proven to be very particularly preferred to use one or more hydrocarbons in very specific quantity ranges in the composition (B).

With a view to solving the problem according to the invention, it has proven to be particularly preferred if the second composition (B) - based on the total weight of the composition (B) - has one or more hydrocarbons in a total amount of 0.5 to 20.0 % By weight, preferably from 1.0 to 15.0% by weight, more preferably from 1.5 to 10.0% by weight and very particularly preferably from 2.0 to 8.0% by weight.

In the context of a particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) - based on the total weight of the composition (B) - has one or more hydrocarbons in a total amount of 0.5 to 20.0 wt. %, preferably 1.0 to 15.0% by weight, more preferably from 1.5 to 10.0% by weight and very particularly preferably from 2.0 to 8.0% by weight.

The hydrocarbon or hydrocarbons can be used as the sole fat constituent in the compositions (B). However, it is very particularly preferred to incorporate at least one hydrocarbon in combination with at least one further constituent in the compositions (B).

Composition (B) very particularly preferably contains at least one fat component from the group of C ₁₂ -C ₃₀ fatty alcohols and at least one further fat component from the group of hydrocarbons.

Solvent in composition (B)

Further work leading to this invention has shown that the use of at least one protic solvent in the composition (B) on contact with the composition (A) also reduces the reaction rate of the C ₁ -C ₆ -alkoxy-silanes.

Protic solvents have at least one hydroxyl group. Without being tied to this theory, it is assumed that the solvents can also react with the C ₁ -C ₆ -alkoxysilanes via their hydroxy group (s), but the reaction between the solvent and C ₁ -C ₆ -alkoxysilanes proceeds more slowly than the analogous reaction between water and C ₁ -C ₆ alkoxysilanes. In total, the hydrolysis and / or condensation reaction of the C ₁ -C ₆ -alkoxysilanes is reduced in this way.

Suitable solvents are, for example, 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and / or benzyl alcohol.

In a further very particularly preferred embodiment, a method according to the invention is characterized in that the second composition (B) has at least one solvent from the group of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2-butylene glycol, dipropylene glycol, Contains ethanol, isopropanol, diethylene glycol monoethyl ether, glycerine, phenoxyethanol and / or benzyl alcohol.

Compositions (B) which contain 1,2-propylene glycol as solvent are very particularly preferred.

1,2-Propylene glycol is alternatively also called 1,2-propanediol and has the CAS numbers 57-55-6 [(RS) -1,2-dihydroxypropane], 4254-14-2 [(R) -1 , 2-dihydroxypropane] and 4254-15-3 [(S) -1,2-dihydroxypropane]. Alternatively, ethylene glycol is also known as 1,2-ethanediol and has the CAS number 107-21-1; alternatively, glycerol is also known as 1,2,3-propanetriol and has the CAS number 56-81-5. Phenoxyethanol has the Cas number 122-99-6.

All the solvents described above are commercially available from various chemical suppliers such as Aldrich or Fluka.

By using the abovementioned solvents in suitable amounts, the rate of film formation starting from the C ₁ -C ₆ -alkoxy-silanes can be influenced to a particularly large extent. For this reason it has proven to be very particularly preferred to use one or more solvents in very specific quantity ranges.

It is very particularly preferred if the second composition (B) - based on the total weight of the composition (B) - one or more solvents in a total amount of 1.0 to 35.0% by weight, preferably from 4.0 to 25.0% by weight, more preferably from 8.0 to 20.0% by weight, and very particularly preferably from 10.0 to 15.0% by weight.

It is very particularly preferred if the second composition (B) - based on the total weight of the composition (B) - one or more solvents from the group of 1,2-propylene glycol, 1,3-propylene glycol, ethylene glycol, 1,2- Butylene glycol, dipropylene glycol, ethanol, isopropanol, diethylene glycol monoethyl ether, glycerol, phenoxyethanol and / or benzyl alcohol in a total amount of 1.0 to 35.0% by weight, preferably from 4.0 to 25.0% by weight, more preferably from 8 , 0 to 20.0% by weight, and very particularly preferably from 10.0 to 15.0% by weight.

Further cosmetic ingredients in composition (B)

In addition to the very particularly preferred ingredients already described above, the composition (B) can also contain one or more further cosmetic ingredients.

The cosmetic ingredients that can optionally be used in the composition (B) can be all suitable constituents in order to impart further positive properties to the agent. For example, a solvent, a thickening or film-forming polymer, a surface-active compound from the group of nonionic, cationic, anionic or zwitterionic / amphoteric surfactants, the coloring compounds from the group of pigments, the substantive dyes, the oxidation dye precursors can be used in the composition (A) , the fatty components from the group of C ₈ -C ₃₀ fatty alcohols, the hydrocarbon compounds, fatty acid esters, the acids and bases belonging to the group of pH regulators, those of perfumes, preservatives, plant extracts and protein hydrolysates.

If the process according to the invention is a process for coloring keratinic material, the composition (B) can very particularly preferably contain at least one coloring compound from the group of pigments and / or substantive dyes.

The person skilled in the art will select these additional substances according to the desired properties of the agents. With regard to further optional components and the amounts of these components used, express reference is made to the relevant manuals known to the person skilled in the art.

pH values of the compositions in the process

In further tests it has been found that the pH values of the compositions (A) and / or (B) can have an influence on the previously described hydrolysis or condensation reactions occurring during use. It was found here that alkaline pH values in particular stop condensation at the oligomer stage. The more acidic the reaction mixture, the stronger the condensation appears to be and the higher the molecular weight of the silane condensates formed during the condensation. For this reason, it is preferred that the compositions (A) and / or (B) have a pH of from 7.0 to 12.0, preferably from 7.5 to 11.5, more preferably from 8.5 to 11 , 0 and most preferably from 9.0 to 11.0.

The water content of the composition (A) is a maximum of 10.0% by weight and is preferably set even lower. In the context of some embodiments, the water content of the composition (B) can also be selected to be low. In particular in the case of compositions with a very low water content, the measurement of the pH value with the usual methods known from the prior art (pH value measurement by means of glass electrodes via combination electrodes or via pH indicator paper) can prove to be difficult. For this reason, the pH values according to the invention are those values which were obtained after mixing or diluting the preparation in a weight ratio of 1: 1 with distilled water.

The corresponding pH value is measured accordingly after, for example, 50 g of the composition according to the invention have been mixed with 50 g of distilled water.

In a further particularly preferred embodiment, a method according to the invention is characterized in that the composition (A) and / or (B) has a pH of 7.0 to 11.5 after dilution with distilled water in a weight ratio of 1: 1 , more preferably from 8.5 to 11.0 and very particularly preferably from 9.0 to 11.0.

To set this alkaline pH, it may be necessary to add an alkalizing agent and / or acidifying agent to the reaction mixture. The pH values in the context of the present invention are pH values that were measured at a temperature of 22 ° C.

Ammonia, alkanolamines and / or basic amino acids, for example, can be used as alkalizing agents.

Alkanolamines can be selected from primary amines with a C ₂ -C ₆ -alkyl parent structure which carries at least one hydroxyl group. Preferred alkanolamines are selected from the group that is formed from 2-aminoethan-1-ol (monoethanolamine), 3-aminopropan-1-ol, 4-aminobutan-1-ol, 5-aminopentan-1-ol, 1-aminopropane -2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1 -Amino-2-methylpropan-2-ol, 3-aminopropane-1,2-diol, 2-amino-2-methylpropan-1,3-diol.

An amino acid in the context of the invention is an organic compound which, in its structure, contains at least one amino group which can be protonated and at least one —COOH or one —SO ₃ H group. Preferred amino acids are aminocarboxylic acids, in particular α- (alpha) -aminocarboxylic acids and ω-aminocarboxylic acids, with α-aminocarboxylic acids being particularly preferred.

According to the invention, basic amino acids are to be understood as meaning those amino acids which have an isoelectric point p1 of greater than 7.0.

Basic α-aminocarboxylic acids contain at least one asymmetric carbon atom. In the context of the present invention, both possible enantiomers can be used equally as specific compounds or mixtures thereof, in particular as racemates. However, it is particularly advantageous to use the naturally preferred isomer form, usually in the L configuration.

The basic amino acids are preferably selected from the group that is formed from arginine, lysine, ornithine and histidine, particularly preferably from arginine and lysine. In a further particularly preferred embodiment, an agent according to the invention is therefore characterized in that the alkalizing agent is a basic amino acid from the group arginine, lysine, ornithine and / or histidine.

Inorganic alkalizing agents can also be used. Inorganic alkalizing agents which can be used according to the invention are preferably selected from the group formed by sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.

Particularly preferred alkalizing agents are ammonia, 2-aminoethan-1-ol (monoethanolamine), 3-aminopropan-1-ol, 4-aminobutan-1-ol, 5-aminopentan-1-ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1-amino-2- methylpropan-2-ol, 3-aminopropan-1,2-diol, 2-amino-2-methylpropane-1,3-diol, arginine, lysine, ornithine, histidine, sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, Sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.

In addition to the alkalizing agents described above, the person skilled in the art is familiar with acidifying agents commonly used for fine adjustment of the pH. Acidifying agents preferred according to the invention are pleasure acids, such as citric acid, acetic acid, malic acid or tartaric acid, and also dilute mineral acids.

Application of compositions (A) and (B)

The method according to the invention comprises the application of the two compositions (A) and (B) to the keratinic material. It is essential for the method that the compositions (A) and (B) come into contact with one another on the keratinic material. As already described above, this contact can be created either by mixing (A) and (B) beforehand or by successively applying (A) and (B) to the keratin material.

The work leading to this invention has shown that the composition (B) containing water (B1) and nonionic surfactants (B2) can in particular have an optimal influence on the low-water silane blend (ie on the composition (A)) when the Compositions (A) and (B) were mixed together before use.

This mixing can be done, for example, by stirring or shaking. It is particularly advantageous to pack the two compositions (A) and (B) separately in two containers, and then transfer the entire amount of the composition (A) from its container to the container in which the second container is located before use Composition (B) is located.

In the context of a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratin material which was prepared by mixing the first composition (A) and the second composition (B) immediately before use.

The two compositions (A) and (B) can be mixed with one another in different proportions.

The composition (A) is particularly preferably used in the form of a relatively highly concentrated, low-water silane blend which is quasi diluted by mixing with the composition (B). For this reason, it is particularly preferred to mix the composition (A) with an excess weight of the composition (B). For example, 1 part by weight (A) can be mixed with 20 parts by weight (B), or 1 part by weight (A) is mixed with 10 parts by weight (B), or 1 part by weight (A) is mixed with 5 parts by weight (B).

In the context of a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinic material which, immediately before use, is obtained by mixing the first composition (A) and the second composition (B) in a quantity ratio (A) / (B) from 1: 5 to 1:20.

In principle, however, it is also possible to use the composition (A) in a weight excess in relation to the composition (B). For example, 20 parts by weight (A) can be mixed with 1 part by weight (B), or 10 parts by weight (A) are mixed with 1 part by weight (B), or 5 parts by weight (A) are mixed with 1 part by weight (B).

Furthermore, it is also conceivable to apply the compositions (A) and (B) successively to the keratin material, so that the contact of (A) and (B) does not come about until the keratin material. In the context of this embodiment, there is preferably no washing of the keratin material between the application of the compositions (A) and (B), i. no treatment of the keratin material with water or water and surfactants.

In one embodiment, only the two compositions (A) and (B) can be used on the keratinic material. In particular when using the method according to the invention for coloring keratinous material, it can also be particularly preferred if not only the two compositions (A) and (B) but also at least one third composition (C) are used on the keratin material.

In a method for coloring keratinic material, the third composition (C) can be, for example, a composition which contains at least one coloring compound from the group of pigments and / or substantive dyes.

• - eine dritte Zusammensetzung (C), die enthält mindestens eine farbgebende Verbindung as der Gruppe der Pigmente und/oder der direktziehenden Farbstoffe.

In the context of a further embodiment, a method according to the invention in which the keratin material is applied is particularly preferred

• - A third composition (C) which contains at least one coloring compound as from the group of pigments and / or substantive dyes.

When using the three compositions (A), (B) and (C), different embodiments are according to the invention.

In one embodiment, it is particularly preferred to produce a mixture of the three compositions (A), (B) and (C) before use and then to apply this mixture to the keratin material.

In the context of a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinic material which, immediately before use, is produced by mixing the first composition (A) with the second composition (B) and a third composition (C ) was obtained,
wherein the third composition (C) contains at least one coloring compound from the group of pigments and / or substantive dyes.

When coloring the keratin material, it can also be particularly preferred to produce a mixture immediately before use by mixing the first composition (A) and the second composition (B) and to apply this mixture of (A) and (B) to the keratin material. The third composition (C) with the coloring compounds can then subsequently be applied to the keratin material.

In a particularly preferred embodiment, a method according to the invention is characterized in that a composition is applied to the keratinic material which was obtained immediately before use by mixing the first composition (A) with the second composition (B) and subsequently thereafter the composition (C) is applied to the keratinous material.

In other words, a particularly preferred method according to the invention is characterized in that, in a first step, a composition is applied to the keratinic material which was prepared immediately before use by mixing the first composition (A) and the second composition (B), and in a second step the third composition (C) is applied to the keratin material.

In addition to the compositions (A) and (B) - or (A), (B) and (C) - a fourth composition (D) can also be applied to the keratin material in the method according to the invention. The fourth composition (D) is particularly preferably used in a dyeing process in order to seal the previously obtained dyeings again. For this seal, the composition (D) can contain, for example, at least one film-forming polymer.

• - eine vierte Zusammensetzung (D), die enthält

mindestens eine filmbildendes Polymer.In other words, a method according to the invention in which the keratin material is applied is also very particularly preferred

• - a fourth composition (D) which contains

at least one film-forming polymer.

Coloring compounds

When using the compositions (A) and (B) - or additionally optionally (C) and / or (D) - in a dyeing process, one or more coloring compounds can be used.

In particular, preparation (B) and / or preparation (C) which is optionally used can additionally contain at least one coloring compound.

The coloring compound or compounds can preferably be selected from the pigments, the substantive dyes, the oxidation dyes, the photochromic dyes and the thermochromic dyes, particularly preferably from pigments and / or substantive dyes.

Pigments in the context of the present invention are understood to mean coloring compounds which at 25 ° C. in water have a solubility of less than 0.5 g / L, preferably less than 0.1 g / L, even more preferably less than 0, 05 g / L. The water solubility can be achieved, for example, by means of the method described below: 0.5 g of the pigment is weighed out in a beaker. A stir fry is added. Then one liter of distilled water is added. This mixture is heated to 25 ° C. for one hour while stirring on a magnetic stirrer. If undissolved constituents of the pigment are still visible in the mixture after this period, the solubility of the pigment is below 0.5 g / L. If the pigment-water mixture cannot be assessed visually due to the high intensity of the pigment which may be present in finely dispersed form, the mixture is filtered. If a proportion of undissolved pigments remains on the filter paper, the solubility of the pigment is below 0.5 g / L.

In a further embodiment, the agent according to the invention or the preparation according to the invention can also contain one or more coloring compounds from the group of organic pigments

The organic pigments according to the invention are correspondingly insoluble, organic dyes or color lakes, for example from the group of nitroso, nitro, azo, xanthene, anthraquinone, isoindolinone, isoindoline, quinacridone, perinone, perylene -, Diketopyrrolopyorrol-, indigo, thioindido, dioxazine, and / or triarylmethane compounds can be selected.

Particularly suitable organic pigments are, for example, carmine, quinacridone, phthalocyanine, sorghum, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680 , CI 11710, CI 15985, CI 19140, CI 20040, CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725 , CI 15510, CI 45370, CI 71105, red pigments with the color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

In a further particularly preferred embodiment, a method according to the invention is characterized in that the composition (B) and / or the composition (C) contains at least one coloring compound from the group of organic pigments, which is selected from the group of carmine, quinacridone, Phthalocyanine, Sorgho, blue pigments with the color index numbers CI 42090, CI 69800, CI 69825, CI 73000, CI 74100, CI 74160, yellow pigments with the color index numbers CI 11680, CI 11710, CI 15985, CI 19140, CI 20040 , CI 21100, CI 21108, CI 47000, CI 47005, green pigments with the color index numbers CI 61565, CI 61570, CI 74260, orange pigments with the color index numbers CI 11725, CI 15510, CI 45370, CI 71105, red pigments with the color index numbers CI 12085, CI 12120, CI 12370, CI 12420, CI 12490, CI 14700, CI 15525, CI 15580, CI 15620, CI 15630, CI 15800, CI 15850, CI 15865, CI 15880, CI 17200, CI 26100, CI 45380, CI 45410, CI 58000, CI 73360, CI 73915 and / or CI 75470.

The organic pigment can also be a colored lacquer. In the context of the invention, the term “colored varnish” is understood to mean particles which comprise a layer of absorbed dyes, the unit of particles and dyestuff falling under the above Conditions is insoluble. The particles can be, for example, inorganic substrates, which can be aluminum, silica, calcium borosilicate, calcium aluminum borosilicate or also aluminum.

The alizarin color varnish, for example, can be used as the color varnish.

Due to their excellent light and temperature stability, the use of the aforementioned pigments in the agents according to the invention is particularly preferred. It is also preferred if the pigments used have a certain particle size. This particle size leads, on the one hand, to a uniform distribution of the pigments in the polymer film formed and, on the other hand, prevents the hair or skin feeling rough after the cosmetic agent has been applied. It is therefore advantageous according to the invention if the at least one pigment has an average particle size D 50 of 1.0 to 50 μm, preferably 5.0 to 45 μm, more preferably 10 to 40 μm, in particular 14 to 30 μm. The mean particle size D ₅₀ can be determined using dynamic light scattering (DLS), for example.

The pigment or pigments can be used in an amount of from 0.001 to 20% by weight, in particular from 0.05 to 5% by weight, based in each case on the total weight of the agent or preparation according to the invention.

The agents according to the invention can also contain one or more substantive dyes as coloring compounds. Direct dyes are dyes that are absorbed directly onto the hair and do not require an oxidative process to develop the color. Substantive dyes are usually nitrophenylenediamines, nitroaminophenols, azo dyes, anthraquinones, triarylmethane dyes or indophenols.

The substantive dyes within the meaning of the present invention have a solubility in water (760 mmHg) at 25 ° C of more than 0.5 g / L and are therefore not to be regarded as pigments. For the purposes of the present invention, the substantive dyes preferably have a solubility in water (760 mmHg) at 25 ° C. of more than 1.0 g / l. In the context of the present invention, the substantive dyes particularly preferably have a solubility in water (760 mmHg) at 25 ° C. of more than 1.5 g / l.

Substantive dyes can be divided into anionic, cationic and nonionic substantive dyes.

In a further preferred embodiment, an agent according to the invention is characterized in that it contains at least one anionic, cationic and / or nonionic substantive dye as the coloring compound.

In a further preferred embodiment, a method according to the invention is characterized in that the composition (B) and / or the composition (C) contains at least one coloring compound from the group of anionic, nonionic and / or cationic substantive dyes.

Suitable cationic substantive dyes are, for example, Basic Blue 7, Basic Blue 26, Basic Violet 2 and Basic Violet 14, Basic Yellow 57, Basic Red 76, Basic Blue 16, Basic Blue 347 (Cationic Blue 347 / Dystar), HC Blue No. 16, Basic Blue 99, Basic Brown 16, Basic Brown 17, Basic Yellow 57, Basic Yellow 87, Basic Orange 31, Basic Red 51 Basic Red 76

Nonionic nitro and quinone dyes and neutral azo dyes, for example, can be used as nonionic substantive dyes. Suitable nonionic substantive dyes are those under the international names or trade names HC Yellow 2, HC Yellow 4, HC Yellow 5, HC Yellow 6, HC Yellow 12, HC Orange 1, Disperse Orange 3, HC Red 1, HC Red 3, HC Red 10, HC Red 11, HC Red 13, HC Red BN, HC Blue 2, HC Blue 11, HC Blue 12, Disperse Blue 3, HC Violet 1, Disperse Violet 1, Disperse Violet 4, Disperse Black 9 known compounds, as well 1,4-diamino-2-nitrobenzene, 2-amino-4-nitrophenol, 1,4-bis- (2-hydroxyethyl) -amino-2-nitrobenzene, 3-nitro-4- (2-hydroxyethyl) -aminophenol, 2- (2-Hydroxyethyl) amino-4,6-dinitrophenol, 4 - [(2-hydroxyethyl) amino] -3-nitro-1-methylbenzene, 1-amino-4- (2-hydroxyethyl) -amino-5- chloro-2-nitrobenzene, 4-amino-3-nitrophenol, 1- (2'-ureidoethyl) amino-4-nitrobenzene, 2 - [(4-amino-2-nitrophenyl) amino] -benzoic acid, 6-nitro-1 , 2,3,4-tetrahydroquinoxaline, 2-hydroxy-1,4-naphthoquinone, picric acid and its salts, 2-amino-6-chloro-4-nitrophenol, 4-ethylamino-3-nitrobenzoic acid and 2-chloro-6- et hylamino-4-nitrophenol.

Anionic substantive dyes are also referred to as acid dyes. Acid dyes are understood as meaning substantive dyes which have at least one carboxylic acid group (—COOH) and / or one sulfonic acid group (—SO ₃ H). Depending on the pH, the protonated forms (-COOH, -SO ₃ H) of the carboxylic acid or sulfonic acid groups are in equilibrium with their deprotonated forms (-COO ^- , -SO ₃ ^- before). The proportion of protonated forms increases with decreasing pH. If substantive dyes are used in the form of their salts, the carboxylic acid groups or sulfonic acid groups are present in deprotonated form and are neutralized with corresponding stoichiometric equivalents of cations in order to maintain electrical neutrality. Acid dyes according to the invention can also be used in the form of their sodium salts and / or their potassium salts.

The acid dyes for the purposes of the present invention have a solubility in water (760 mmHg) at 25 ° C. of more than 0.5 g / L and are therefore not to be regarded as pigments. For the purposes of the present invention, the acid dyes preferably have a solubility in water (760 mmHg) at 25 ° C. of more than 1.0 g / l.
The alkaline earth salts (such as calcium salts and magnesium salts) or aluminum salts of acid dyes often have a poorer solubility than the corresponding alkali salts. If the solubility of these salts is below 0.5 g / L (25 ° C, 760 mmHg), they do not fall under the definition of a substantive dye.

An essential feature of acid dyes is their ability to develop anionic charges, the carboxylic acid or sulfonic acid groups responsible for this usually being linked to different chromophoric systems.

The water solubility of the anionic substantive dyes can be determined, for example, in the following way. 0.1 g of the anionic substantive dye are placed in a beaker. A stir bar is added. Then 100 ml of water are added. This mixture is heated to 25 ° C. on a magnetic stirrer while stirring. It is stirred for 60 minutes. The aqueous mixture is then assessed visually. If there are still undissolved residues, the amount of water is increased - for example in steps of 10 ml. Water is added until the amount of dye used has completely dissolved. If the dye-water mixture cannot be assessed visually due to the high intensity of the dye, the mixture is filtered. If a portion of undissolved dyes remains on the filter paper, the solubility test is repeated with a larger amount of water. If 0.1 g of the anionic substantive dye dissolves in 100 ml of water at 25 ° C., the solubility of the dye is 1.0 g / L.

Film-forming polymers

The preparations described above, in particular preparations (B), (C) and (D), very particularly preferably preparation (D), can contain at least one film-forming polymer.

Polymers are understood to mean macromolecules with a molecular weight of at least 1000 g / mol, preferably of at least 2500 g / mol, particularly preferably of at least 5000 g / mol, which consist of identical, repeating organic units. The polymers of the present invention can be synthetically produced polymers which are produced by polymerizing one type of monomer or by polymerizing different types of monomers which are structurally different from one another. If the polymer is produced by polymerizing one type of monomer, it is called a homo-polymer. If structurally different types of monomers are used in the polymerization, the resulting polymer is referred to as a copolymer.

The maximum molecular weight of the polymer depends on the degree of polymerisation (number of polymerised monomers) and the batch size and is also determined by the polymerisation method. For the purposes of the present invention, it is preferred if the maximum molecular weight of the film-forming, hydrophobic polymer (c) is not more than 10 ⁷ g / mol, preferably not more than 10 ⁶ g / mol and particularly preferably not more than 10 ⁵ g / mol amounts.

In the context of the invention, a film-forming polymer is understood to mean a polymer which is able to form a film on a substrate, for example on a keratinic material or a keratinous fiber.

A stir bar is added and the mixture is warmed to 25 ° C on a magnetic stirrer while stirring. It is stirred for 60 minutes. The aqueous mixture is then assessed visually. If the polymer-water mixture cannot be assessed visually due to the high turbidity of the mixture, the mixture is filtered. If a proportion of undissolved polymer remains on the filter paper, the solubility of the polymer is less than 1% by weight.
